94 Ford Bronco - When I start my Bronco in the morning (or whenever it's cold), I can hear water flowing behind the dash board on the passenger side where the heater core is (I think). I've checked for visible leaks and haven't found any. I've called a couple of dealerships and they both told me it sounds like air in the cooling system. Has anyone experienced this? If so, do you know how to remedy this pronblem? Thanks!
Does your thermostat have a little whole with a piece of metal (bleeder valve) that moves around in it? If it does make sure it is at the 12 o'clock position and that the little piece metal moves freely this will allow the air to bleed out. Hope this helps and Good Luck,
